IMPROVEMENT IN'Y MOULDING--CUTTER The Schedule referred to in thescLetters Patent and making part of the same.

I, THOMAS J. SHANNON, ot' Lawrenceburg, VDearhorn county, Indiana, have invented a ne'w and useful Friezing or Moulding-Cutter, of which the following is a speciiication.

Naw-re and Object of the Invention.

My invention relatcsrto a form of rotary cutter for the manufacture of wooden mouldings and other' ohjects, whose periphery is turned from centres eccentric to that of its shaft, so. as to ahrd proper lead or salency of the cutting-edges, and to relieve the periphery of the cutter from contact with the stuff.

General Description 'with Reference to the Drawings.

Figures 1 and-2 represent the opposite ends of my cutter.

Figure 3 is a side elevation thereof.

A is a short mandrel, which occupies, during construction, a corresponding eye or hole in the cutter, and has, in addition to the customary pricks or centres B B', for the points of the lathe in turning of .the concentric portions, two other pairs of centres C C', D D', equidistant from and on opposite sides ot' the centres B B'.

From the centres G C is turned' the periphery c of the double-pointed or right-and-left blade or bit c, said periphery having thereby sulcient cccentricity imparted to it for thepoint of the blade to readily enter the substance of the stut, without Athe loss of' power and imperfect cutting-action to which the heads with concentric peripheries are subject.
